The pfiTDFXform is a convenience class of the general pfiXformer and
does exactly this.
A pfiXformer has a pfiInput for getting and processing events.
You can hook up libpfutil event streams or set your own callbacks:
        pfiInput::setEventStreamCollector()
        pfiInput::setEventStreamProcessor()
The pfiTDFXform fills in the intput handling callback with a special mouse
handling routine, pfiProcessTDFXformerMouseEvents():
The C-API is rather incomplete for doing custom
Xformers so I recommend using the C++ API.
The documentation is also a bit thin but the source code of relevance is
in /usr/share/Performer/src/lib/libpfui/
        pfiInputXform.[Ch] and pfiXformer.[Ch]

src.
